The artifact WebFetch tool now probes the sharing status of an artifact before reading it. The mode is now shown in descriptive human-readable form instead of raw enum values:
"owner"→ "a private page on claude.ai""org"→ "a page shared with your organization""users"→ "a page shared with specific users"- Live-shared → "on claude.ai (viewers see updates immediately)"
- Unknown mode → "others (unrecognized share mode — treating as shared)"
Evidence
Share mode labels (search for "a private page on claude.ai" and "your organization")
Strings lifted out of the shipped bundle, so the claim above can be checked against them.
